[FNI18300]

In coherence with the geosolutions-it/MapStore2#11256 issue which provide a way to display version of a deploy plugin in contexte creation, the proposal :

• add version field in index.json
• populate this field with the value in version.txt file
• build the zip with the provided value

Ok this is a correct behabior.
Just a question about the version.txt file presents at root folder : What is the usage or the aim of this file ?

From my understanding, this file contained the plugin version. This information is redundant with information in package.json version.

May be we could remove the version.txt file ?
